While much of the mid-Atlantic was digging out from a winter storm that brought heavy snow to the Washington, D.C., area, a second storm is expected to follow, bringing snow, sleet and freezing rain along a more northerly track from Colorado to Maine.

Heavy snow, freezing rain and temperatures as much as 35 degrees below seasonal averages are set to hit large parts of the United States as a string of storms confirm that winter is far from over.
